Question

A system of equations is shown below.

Answer 1

Answer:

the first equation the y intercept is -2

Answer 2

Answer:

Answer is 13.

Step-by-step explanation:

EQ 1: y = 2x^2-x-2  

EQ2: y = x^2+3x -5

Set the two equation equal to each other:

2x^2-x-2 = x^2+3x -5

Simplify:

x^2 -4x +3 = 0

(x - 3 ) (x - 1) = 0

Solutions:

x = 3 and x= 1

Plug these values into each of the original equations and see which on gives you the highest value.

Solution set:

y={13, -1, 13, -1}

Answer is 13
